lows:
Thereisafurtherrestriction:Iftherearetwodistributedsitestransmittingtoeachother,
theymustbothusethesameRFP. Thisrequirement,togetherwithuseofshiftedtransmis‐
sionphase(item3below),ensuresthatcommunicatingdistributedsitestonotinterfere
witheachotherbytransmittingsimultaneously.
TwoGSUmanagedsitestransmittingwithshiftedtransmissionphaseandusingthesame
RFP,transmitonehalfaRFDapart(seeFigure14‐3above).

describedinstep1.
